RaspberryPi Boards

Hardware versions/revisions

Several different boards have been found probably from different assembly lines, and the following table tries to help you identify your board for better troubleshooting.
These differences are being debated on raspberrypi.org on this thread [1]

For what we can see for model B boards there are mainly two versions that differ on the type RAM used, Samsung (S) and Hynix (H).

D1 shorted when attaching a Neewer HDMI to VGA adapter. The adapter has had no other tests and the raspberry pi's HDMI output has not been connected to any other devices before or since.

First had problems (freezing, no LAN, etc.) due to low quality power supply - cheap ebay adaptor. Solved with own PSU construction with 7805 stabiliser adjusted to 5.25V. Now works OK with Raspbian “wheezy”, but not yet tested extensively.

With extra header P5, missing fuses F1 and F2, and with mounting holes just like BS1233

Weird stability problems. Can build Quake3, and can play it for a little while, but eventually locks up (black screen, loses ethernet link). Putting it in the Adafruit case seems to exacerbate the problem.

Highest temp measured by vcgencmd measure_temp is 53.5C. Last measured temp before lockup was 53.0C

Problem occurs with both the Adafruit power supply as well as my Nexus 7 2A supply.

Tested with at least 3 different Micro-USB cables.

Tested with the 4GB Dane-Elec Class 4 MicroSD card from Adafruit, as well as an 8GB Class 10 SanDisk full-size SD card.

Voltages:

Idle, with HDMI only

5.06V (polyfuse in)

4.82V (polyfuse out)

Idle, with HDMI, keyboard and mouse

5.04V (polyfuse in)

4.77V (polyfuse out)

Running Quake (with HDMI, keyboard, mouse, and network)

4.98V (polyfuse in)

4.55V (polyfuse out)
